Cost of Rehabilitation of Water Distribution Systemsby Peter K. Mac Ewen, Chester Water Authority, Chester, United States,
Abstract: The Chester Water Authority was established in 1868 and supplies water to residential and industrial customers in three counties in Southeastern Pennsylvania, and in addition, wholesales water to two major water utilities in the state of Delaware by way of an interstate connection. From 1974 to date, the Authority has cleaned and lined approximately 23 miles of water main at a cost of approximately 8.5 million dollars. The 1991 cost per foot at Chester Water Authority for cleaning and lining was $65.00. The long range goal of the Authority is to continue with the cleaning and lining program and replacement of water mains and to continue to replace all lead and galvanized services so that within 35 years the majority of the Authority's distribution system will have been rehabilitated both by the cleaning and lining process and the replacement of water mains.
